TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 349,145, datedSeptember 14, 1886.

Application filed July 16, 1886. Serial No. 208,208. (No model.)

To all whom it may concern.-

Be it known that we, MARTIN M. DEPUY and WILLIAM B. DEPUY, of Rowland,in the county of Pike and State of Pen nsylvani a, have invented a newand useful Improvement in Tricycles, of which the following is a full,clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of our improved tricycle, the seat being removedand the seatsupporting springs shown in section. Fig. 2 is a frontelevation of a part of the same. Fig.

. 3 is a side elevation of the same, the near forward wheel beingremoved, and parts being broken away. Fig; 4 is a sectional frontelevation of the same, taken throughthe broken line a" a; 00, Fig. 1.

The object of this invention is to provide tricycles constructed in sucha manner that they can be driven at greater speed and with more casethan tricycles constructed in the ordinary manner, and which can beeasily turned and accurately guided.

The invention consists in the constructio and combination of variousparts of the tricycle, as will be hereinafter fully described. Arepresents the frame of the machine, to the rear ends of the side barsof which is journaled the drive-wheel B. To the projecting ends of thejournals of the drive-wheel B are rigidly attached cranks G, which standat an angle of about forty-five degrees with each other, so that theycan never be on the deadpoint at the same time. To the cranks O arepivoted the rear ends of connecting-bars D,

the forward ends of which are pivoted to the downwardly projecting endsof the upper parts cf the jointed levers E at a little distance belowtheir joints. The lower ends of the jointed levers E are pivoted to therearwardly-inclined lower ends of hangers F, the upper parts of whichare rigidly attached to the side bars of the frame A. To the lower partsof the jointed levers E, and about upon a level with the forward ends ofthe connecting-bars D, are pivoted the rear ends of the connecting-barsG, the forward ends of which are pivoted to the lower ends of thehandlevers H. The hand-levers H are pivoted to the forwardly-inclinedupwardly-projecting ends I of the hangers F, or other suitable supportsattached to the side bars of the frame A. To the upper parts of thelevers H, and about equally distant from their joints with the forwardends of the connecting-bars G, are piv oted the forward ends of theconnecting-bars J, the rear ends of which are pivoted to the upper endsof the jointed levers E at about the same distance from their joints asthe ends of the bars D G, or at a little greater distance. With thisconstruction long cranks can be worked on the drive-whee1 journals withacomparatively short movement of the handlever, so that great power canbe applied to the drive wheel cranks, and consequently great speedattained.

To frames K, or other supports attached to the side bars of the frame A,are' secured the lower parts of the springs L, to'the upper parts ofwhich is attached the drivers seat M.

In bearings attached to the side bars of the frame A, a little in frontof the drive-wheel-B, is journaled a shaft, N, to the middle part ofwhich is attached an arm, 0, having a friction-roller, P, pivoted to itsslotted outer end.

One of the journals of the shaft N projects, and to it is attached theend of a lever, Q, the other end of which extends back into such, aposition that it can be readily reached and operated by the rider fromhis seat to swing the roller P against the face of the drive-wheel B,and thus check or stop its movement.

R are the guide-wheels, the inner parts of the axle-arms S of which restupon the end parts of the axletree T, and are pivoted at points near theinner ends of the wheel-hubs to the ends of the said axle-tree. Themiddle .part of the axle-tree T is rigidly attached to the lower side ofthe forward end of the frame A. To the inner ends of the axle-arms S arepivoted the forward ends of the connectingbars U, the rear ends of whichare pivoted to the ends of a lever, V, shorter than the axletree T, butlonger than the space between the inner ends of the axle-arms S.

In the rear edge of the lever V, upon the opposite sides of, atequal'distances from, and near, its center, are formed slots V toreceive pins X, rigidly attached to a cross-bar of the 30 the lever.

frame A, and one or the other of which serve as fulcrums, according asone or the other end of the lever V is pushed forward. To the center ofthe lever V, between the slots XV, is

5 rigidly attached the rear end of an arm, Y,

the forward end of which is slotted to receive the rear edge of theguide-board Z, and has a roller, a, pivoted to its slotted forward endto lessen the friction against the said rear edge of the saidguide-board.

The rear edge of the guide-board Z is concaved upon the arcs of twocircles, having their centers in the axes of the fulcrum-pins X, thesaid arcs intersecting in the central I 5 line of the arm Y when thelever V is parallel with the axletree T, to which the said guideboard Zis rigidly attached. To the end parts of the lever V are attached restsb, for the operator to place his feet upon when riding upon the machine,and which are inclined upward toward their forward ends, so that theoperators feet will rest easily upon them. \Vith this construction, whenthe rider forces the left-hand end of the lever V forward, it turns uponthe right-hand fulcrum-pin, X, so that the left-hand wheel, R, will beturned back by the long arm of the lever V, and will be moved fartherthan the right-hand wheel R, which will be turned forward by the shortarm of By this construction the machine can be turned within a smallspace, and can be guided with ease and precision.

Having thus fully described our invention, we claim as new and desire tosecure by Let- 3 5 ters Patent 1. In a tricycle, the combination, withthe frame A and the drive-wheel B, of the crankarms 0, attached to thejournals of the said drive-wheel, the jointed levers E,fulcrumed attheir lower ends to hangers attached to the frame A, the bars D,connecting the said lever E with the crank-arms (l of the drivewheel,the hand-levers H and the bars G J, connecting the said jointed leverswith the said hand-levers H above and below their fulcrum-points,substantially as herein shown and described, whereby the tricycle can bedriven at great speed, as set forth.

2. In a tricycle, the combination, with the frame Aand the drive-wheelB, of the recessed arm 0, provided with a roller, 1, the shaft N,journaled to the frame A, and carrying the arm 0, and the hand-lever Q,attached to the said shaft, substantially as herein shown and described,whereby the movement of the drivewheel can be readily checked orstopped, as set forth.

3. In a tricycle, the combination, with the frame A, the axle-tree '1,and the guidewheels R, of the axle-arms S, pivoted to the saidaxle-tree, the bars U, pivoted to the said axle-arms, and thefoot-leverV, provided with foot-rests b, having two slots, \V, in itsrear edge to receive the two fulcrum-pins X, attached to a cross-bar ofthe frame A, and pro vided with a rigid forwardly-projecting arm, Y,slotted at its forward end to receive the roller a, and the recessedrear edge of the guide-board Z, substantially as herein shown anddescribed, whereby the tricycle can be readily turned and accuratelyguided, as set forth.
